A method of obtaining and merging volumetric data and surface data of a patient's dentition for use in designing and/or manufacturing a prosthodontic component, such as a drill guide, an implant, or other prosthodontic appliance, for example. A plurality of radio-opaque markers are temporarily secured directly to a patient's dentition. Surface data is then obtained, such as by scanning the patient's dentition with the markers or alternatively, by taking an impression of the patient's dentition with the markers, forming a physical model that includes analogs of the markers, and scanning the physical model. Either before or after the surface data is obtained, an anatomical, volumetric image data set of the patient's dentition is obtained via a volumetric scan of the patient's dentition with the markers appearing in the image data set. The markers appearing in both the volumetric data set and the surface data set are used by suitable computer software to merge the volumetric and surface data sets to form a merged image data set and to generate a combined model of the patient's dentition from which a surgical drill guide or other prosthodontic appliance may be designed and manufactured.

The present invention pertains to an orthopedic support having a flexible inner member and an exo-skeleton that is molded directly onto the flexible inner member. One aspect of the invention relates to a wrist support having a thumb spica. The wrist support includes a molded plastic exostructure supplying support for resisting motion of said wrist. An inner fabric support is attached to said molded exostructure for providing cushioning to the wrist area. A separate, attachable thumb spica member is provided for optionally configuring the wrist support to include a thumb spica. Other embodiments include an orthopedic support having an attachable stay; a web bridge that extends across and supports the web of the hand; an adjustable wrist support having an adjustable forearm portion that can accommodate various sizes of forearms; a wrist brace having a space to accommodate the web of the hand; and a support having an interior padding member, with the padding member itself having a support structure molded onto the padding. Another aspect of the invention relates to a method of molding the exostructure onto a central core that is placed inside a mold.
